My Christmas wish for the next Canon EOS Camera / DSLR

To have a button or a way to tag/rate images. Much like how we can do it on a PC or a Mac, why not make it possible in camera also. That way, I will not have to wait until I get home, download the images and then scan through all the files again to pick the ones that work better. This function would certainly come in useful on days when I have to churn out express highlights on a wedding day. Let’s hope Canon take this suggestion into consideration and see some helpful improvements in the next round of camera updates! And if I am allowed 2 wishes… someone please present me with a free Canon EOS 1D-X!!! wahahahaha
